HOSE-COUPLING.

To all whom it may concern:

Be it known that we, J OI-IN LEHMANN and MATHIAS WOLTEK, citizens of theUnited States, residing at l/Vellsville, in the county of Allegany,State of New York, have invented a new and useful I-Iose-Coupling, ofwhich the following is a specification.

It is the object of this invention to pr0 vide a hose coupling which mayreadily be united, without rotating the component elements of thecoupling, the elements of the coupling being adapted to be slidtogether, and to interlock automatically.

Another object of the invention is to provide novel means for holdingthe component elements of the coupling together, and to provide novelmeans for holding the constituent elements of the structure in proper,operative relation with respect to each other.

The drawings. .show typical embodiments merely, and it to be understoodthat changes, properly falling within the scope of what is claimed, maybe made without departing from the spirit of the invention.

In the drawings, Figure 1 shows the invention in longitudinal section;Fig. 2 is a transverse section on the line 22 of Fig. 1; and Fig. 3 is adetail perspectiveof the latch.

The invention includes a primary member 1, and a secondary member 2,both tubular in structure, and threaded at their remote ends, as shownat 3, or otherwise constructed so as to receive and hold the meetingends of two sections of hose. The primary section 1 is recessed in itsend face, as shown at 4, to receive a tongue 5, outstanding from the endface of the secondary section 2. The end of the primary section 1 istapered, as shown at 6, to fit in the conical bore 7 of the secondarysection 2. In the interior of the secondary section 2, are oppositelydisposed recesses 8, defining shoulders 9 and 10. In the primary section1, are oppositely disposed chambers 11, adapted to receive the butts 12of latches, the shanks 1 1 of which extend longitudinally of the primarysection 1, in the interior thereof, the shanks 14 of the latchesregistering in grooves 15 in the primary section 1. At their outeredges, the latches are provided with heads 16, adapted to engage theshoulders 9 of the secondary section 2, to hold the members 1 the butts12 of the latches being pivotally mounted upon pins 19 extendingtransversely of the chambers 11,

and terminally mounted in the primary member 1. The remote faces of theheads 16 of the latches are inclined, as shown at 17 and resilient tips18 may be mounted upon the ends of the latches, these tips being adaptedto be compressed against the shoulders 10, as seen clearly in Fig. 1.

Spring plates 20 are provided, these spring plates being secured bymeans of screws 21 or the like, to the primary section 1. The springplates 20 extend longitudinally of the coupling, their free endsregistering slidably in grooves 22 in the inner faces of the shanks 1 1of the latches. Although the ends of the spring plates 20 are free toslide longitudinally of the grooves in the latches, these grooves are ofsubstantially the same width as the springs 20, and by thisconstruction, it will be seen that when the ends of the springs 20 areseated in the grooves 22, the springs 20 cannot move laterally upon theretaining member 21. Thus, the spring plates 20 are at all timesmaintained in proper relation with respect to the latches which theyactuate.

In the outer face of the primary section 1, are oppositely disposedseats 23. Push buttons are included in the structure, these push buttonscomprising plates 24: and integrally formed shanks 25, the plates 24registering in the seats 23 against rotation. The push buttons furtherinclude heads 26, which are threaded into the shanks 25. These heads 26of the push buttons are provided with kerfs. Upon the shanks 1a of thelatches are transverse ribs 27 adapted to register in the kerfs.

In practical operation, the inclined face 17 of the latch will engagethe tapered bore 7 of the secondary member 2, forcing the free ends ofthe latches inwardly, against the action of the spring plates 20. Thespring plates 20 will, however, when the members 1 and 2 are broughttogether, serve to actuate the heads 16 of the latches into engagementwith the shoulder 9 of the secondary member 2, as shown in Fig. 1 of thedrawings, thus holding the primary member 1 and the secondary member 2firmly together. Therefore, in order to unite two sections of hose orpipe, it is necessary merely to thrust the end of the primary memberinto the end of the secondary member 2, the members 1 and 2automatically locking together. As hereinbefore pointed out, owing tothe fact that the free end of the spring 20 is engaged in the grooves 22of the latch, the spring plate 20 cannot swing laterally; thus thespring is held at all times in a position operative to actuate thelatch.

The component parts of the push button may be separated by unscrewingthe head 26 from the shank 25. This head 26 serves to hold the pushbutton in place within the primary member 1. However, by reason of thefact that the rib 27 which is upon the shank 14 of the latch, registersin the kerf of the head 26, the head 26 is prevented from rotating inthe shank 25 of the push button and thus the parts of the push buttonare held together, the plate portion 24 of the push button being heldwithin the seat 23 provided for its reception.

Having thus described the invention, what is claimed. is

1. A coupling comprising a primary member and a secondary member; alatch pivoted to the primary member and adapted to engage the secondarymember to hold the members assembled; resilient means for actuating thelatch to engage the secondary member; and a push button slidable in theprimary member to move the latch out of engagement with the secondarymember, the button consisting of removably connected parts, one of whichengages the primary member against rotation, and the other of whichengages the primary member to prevent the withdrawal of the button, thelast named part and the latch being provided with interengaging elementsto hold said parts against rotation with respect to the other part.

2. A coupling comprising a primary member and a secondary member; alatch pivoted in the primary member and adapted to engage the secondarymember to hold the members assembled; a spring plate disposed within theprimary member and bearing at one end against the latch to actuate thelatch to engage the secondary member; a connecting element uniting theother end of the plate with the primary member; there being alongitudinal groove in the latch adapted to receive the end of the plateslidably; and to prevent the plate from tilting laterally upon theconnecting element; and means operable from the eX- terior of theprimary member for tilting the latch out of engagement with thesecondary member.

In testimony that we claim the foregoing as our own, we have heretoafiixed our signatures in the presence. of two witnesses.
